Comparison of IPv6 support in operating systems

This is a comparison of operating systems in regard to their support of the IPv6 protocol.

LibreELEC	9.2.1	Yes	Yes	Yes	Yes
Mageia	7+	Yes	Yes	Yes	Yes	Mageia has had full support for IPv6 only and IPv4 + IPv6 since Mageia 7, as well as continuing to support IPv4 only systems.[15]
macOS	Mac OS X 10.7 (Lion)	Yes	Yes	Yes[16]	Yes[17]	Versions 10.7 through 10.10 often prefer IPv4 even when working IPv6 connectivity is available.[18] Versions 10.11 and up will prioritize IPv6 Traffic in spec with Happy Eyeballs.[19]

PlayStation	4 v3.50	No	No	Yes[24]	?
	5	Yes	Yes	Yes	?

Windows NT (includes Windows 10 Mobile, and Xbox One onwards)	5.1 (XP)	Yes	No	Add-on[9]	No	Windows XP users can use Dibbler, an open source DHCPv6 implementation. --update: Windows XP fully supports IPv6- but NOT IPv6 DNS queries (nslookup)[30]
	6.x (Vista, 7, 8, 8.1), 10 RTM-Anniversary Update	Yes[31]	Yes	Yes[9]	No	rdnssd-win32 provides an open source implementation of ND RDNSS[32]

Windows Mobile	6.5	Yes	Yes	Lite[33]	No	If the OEM explicitly unsets the SYSGEN_TCPIP6 pre-processor symbol, the built image will not have any IPv6 capabilities.

Notes

• Operating systems that support neither DHCPv6 nor SLAAC cannot automatically configure unicast IPv6 addresses.
• Operating systems that support neither DHCPv6 nor ND RDNSS cannot automatically configure name servers in an IPv6-only environment.
